ABSTRACT.
Leaf rust (caused by Puccinia triticina) is one of the most important diseases of wheat in Uruguay, and breeding for resistance to this disease is a priority for the INIA wheat program. Knowledge of the effective resistance genes present in the germplasm is relevant when selecting for effective and more durable resistance. The leaf rust resistance present in six adapted wheat cultivars that are parents of many advanced lines was studied. Races of P. triticina with different virulence combinations were used to determine which seedling resistance genes might be present in the six cultivars and/or derived lines. Genetic analysis of seedling and adult plant resistance (APR) was conducted on BC1F2 and F3 generations from crosses of four cultivars with the susceptible cultivar Thatcher. The presence of APR genes Lr13 and Lr34 was confirmed with crosses of the four cultivars and Thatcher lines with these genes. A genetic marker associated with Lr34 was used to postulate the presence of this gene in all cultivars. The cultivars and resistance genes postulated to be present were: Estanzuela Calandria Lr3bg, Lr16 and Lr24; Estanzuela Federal Lr10; Estanzuela Halcón Lr10, Lr14a, and Lr16; INIA Tijereta and INIA Garza Lr16, Lr24 and Lr34; and INIA Torcaza Lr10 and Lr24. Only Lr16 and Lr34 remain effective to the predominant pathotypes. Additional ineffective seedling resistance that could not be identified was present in E. Federal, I. Tijereta and I. Torcaza. Unknown APR gene(s) could be present in E. Calandria and E. Federal.

RESUMEN:La fiebre Q es una zoonosis distribuida mundialmente, causada por Coxiella burnetii. Los bovinos, ovinos y caprinos son la fuente más frecuente de infección en humanos, en los que la enfermedad es de notificación obligatoria ante el Ministerio de Salud Pública. Revisamos las publicaciones que describen casos de fiebre Q en humanos en Uruguay, con foco en sus características epidemiológicas, y discutimos las pruebas diagnósticas disponibles localmente. Se incluyeron nueve trabajos publicados e información del registro de enfermedades profesionales. Colectivamente fueron analizadas 2.715 personas con sospecha de fiebre Q entre 1956-2019, siendo 959 (35,3%) seropositivas. Los diagnósticos se basaron en serología, clínica y/o antecedentes de exposición laboral. Epidemiológicamente, el ganado o material proveniente del mismo fueron considerados las fuentes más probables de exposición en la mayoría de los casos. Según el ámbito de ocurrencia, no sistemáticamente reportado, los casos se registraron principalmente por exposición a ovinos y bovinos en frigoríficos o en la cadena cárnica (positivos/evaluados: 863/1540; seropositivos sintomáticos: 585); y en menor medida a bovinos lecheros (sector lácteo (positivos/evaluados:20/58; seropositivos sintomáticos: 17) y laboratorio diagnóstico (positivos/evaluados:2/4; seropositivos sintomáticos: 1)), o rumiantes silvestres (seropositivos/evaluados:25/117; seropositivos sintomáticos: 17). Hipertermia, cefaleas y sudoración fueron reportados. La inhalatoria fue asumida como la vía de infección en todos los casos. Actualmente no están disponibles localmente pruebas de PCR para detección de C. burnetii en humanos, siendo una limitante en el diagnóstico, particularmente en etapas tempranas. La colaboración interdisciplinaria de profesionales de salud humana y animal es esencial en el abordaje de esta zoonosis.
SUMMARY:Q fever is a globally distributed zoonosis caused by the bacteria Coxiella burnetii. Bovines, sheep and goats are the most frequent source of infection in humans, and it is mandatory for the latter to report the disease to the Ministry of Public Health. We reviewed the literature describing cases of Q fever in humans in Uruguay, focusing on epidemiological characteristics, and we discussed the diagnostic tests locally available. Nine published studies were included in the review, as well as the information in the professional diseases registry. 2.715 people with a suspicion of Q fever were collectively analyzed between 1956-2019, 959 (55.3%) of them being seropositive. Diagnosis were based on serology, clinical examination and/or a history of exposure while working. Epidemiologically, the cattle or material originating in it were considered as the most probable sources of exposure in most cases. Depending on the context cases arose, which were not systematically reported, they were mainly caused by exposure to sheep and cows in meat processing plants or in the meat chain (positive/evaluated: 863/1540; seropositive or symptomatic: 585); and to a lesser extent dairy cattle (milk sector (positive/evaluated: 20/58; symptomatic seropositive: 17) and diagnostic laboratory (positive/evaluated: 2/4; symptomatic seropositive: 1)) or wild ruminants (positive/evaluated: 25/117; symptomatic seropositive: 17). Hyperthermia, headaches and sweating were reported. In all cases inhalation was adopted as the source of infection. Today, there are no PCR tests to detect C. burnetii in humans available locally, what constitutes a limitation to diagnosis, in particular in early stages. Interdisciplinary collaboration between animal and human health professionals is key to approach this zoonosis.
