“…For example, even if a study has identified variations in B. vogeli infection in dogs apparently associated with peaks in the tick vector population [ 184 ], evidence indicates that this protozoan may infect dogs at any period of the year in some regions, regardless of the season [ 120 ]. On the other hand, myiasis by C. hominivorax in dogs and cats presents a clearly defined seasonal pattern in Brazil, peaking during the hottest months of the year [ 59 - 61 , 65 ].…”

Dogs and cats in Brazil serve as primary hosts for a considerable number of parasites, which may affect their health and wellbeing. These may include endoparasites (e.g., protozoa, cestodes, trematodes, and nematodes) and ectoparasites (i.e., fleas, lice, mites, and ticks). While some dog and cat parasites are highly host-specific (e.g., Aelurostrongylus abstrusus and Felicola subrostratus for cats, and Angiostrongylus vasorum and Trichodectes canis for dogs), others may easily switch to other hosts, including humans. In fact, several dog and cat parasites (e.g., Toxoplasma gondii, Dipylidium caninum, Ancylostoma caninum, Strongyloides stercoralis, and Toxocara canis) are important not only from a veterinary perspective but also from a medical standpoint. In addition, some of them (e.g., Lynxacarus radovskyi on cats and Rangelia vitalii in dogs) are little known to most veterinary practitioners working in Brazil. This article is a compendium on dog and cat parasites in Brazil and a call for a One Health approach towards a better management of some of these parasites, which may potentially affect humans. Practical aspects related to the diagnosis, treatment, and control of parasitic diseases of dogs and cats in Brazil are discussed.

“…It is hypothesized that unknown volatiles produced during changed physiological and/or pathological processes – related in one example to otitis externa and, in the other, to the breakdown of products of urine or vaginal discharges – may be responsible for the attraction of gravid females to the ear and vulva regions. The ears of dogs in Brazil were reported to be the site most infested with larvae of C. hominivorax , with otitis being the main predisposing condition leading to myiasis (Cramer‐Ribeiro et al , 2003).…”

“…Obligate traumatic myiasis‐causing fly species can also infest dogs, but there have been only a few reported cases. The New World screwworm fly, Cochliomyia hominivorax (Coquerel), which is responsible for severe economic losses in livestock in the New World, has infested many local dogs in Brazil (Cramer‐Ribeiro et al , 2003). Larvae of the Old World screwworm fly, Chrysomya bezziana Villeneuve, occurring in Africa and Asia, was found in the wounds of dogs (Chemonges‐Nielsen, 2003).…”

. In the province of Al Hoceima, northern Morocco, and on two farms in Hungary, dogs were inspected for the presence of traumatic myiasis. Nine and four infested dogs were found in Morocco and Hungary, respectively. All the larvae and adults reared from them in the laboratory were identified as Wohlfahrtia magnifica (Schiner) (Diptera: Sarcophagidae). To our knowledge, these are the first cases of wohlfahrtiosis in dogs to be reported in these countries. All infested animals lived close to livestock, where wohlfahrtiosis was endemic. Infested body sites included limbs (six cases), external genitalia (two), ears (three), nose (one) and neck (one). Developing larvae caused severe welfare problems and tissue destruction in most cases. Although the number of cases reported here is small, wohlfahrtiosis in dogs may be very important from an epidemiological perspective because farm and stray dogs can act as both reservoirs and carriers of this parasitic fly species. Therefore, education of dog owners concerning the risk factors in endemic regions is recommended in order to reduce the prevalence of wohlfahrtiosis in dogs and thereby in livestock. Both owners and veterinarians should pay regular attention to any wounds and to the natural orifices of dogs, especially during the fly seasons. environment for developing maggots. Dogs confined outdoors are most susceptible to fly strike, especially those which have faecal or urine-stained coats, draining wounds or inflamed tissues (e.g. otitis externa, pyometra or infected paraproctal glands).Sarcophagid flies can also cause facultative myiasis in dogs: Principato et al. (1994) reported a rare case of an Italian dog with traumatic myiasis caused by larvae of Sarcophaga haemorrhoidalis (Fallen). Obligate traumatic myiasis-causing fly species can also infest dogs, but there have been only a few reported cases. The New World screwworm fly, Cochliomyia hominivorax (Coquerel), which is responsible for severe economic losses in livestock in the New World, has infested many local dogs in Brazil ( Cramer-Ribeiro et al. , 2003 ). Larvae of the Old World screwworm fly, Chrysomya bezziana Villeneuve, occurring in Africa and Asia, was found in the wounds of dogs ( Chemonges-Nielsen, 2003 ). The movement of these exotic myiasis-causing fly species, as well as the Tumbu fly ( Cordylobia anthropophaga Blanchard), between continents in infested dogs carries a potential threat of introductions to Europe and other continents where they do not yet exist ( Anon., 1987;Chermette, 1989;Fox et al. , 1992;Hendrix et al. , 1995;Dongus et al. , 1996;Chemonges-Nielsen, 2003;Ferroglio et al. , 2003 ). Wohlfahrt ' s wound myiasis fly, Wohlfahrtia magnifica (Schiner), which is one of the most important obligate traumatic myiasis-causing species in the Palaearctic zone, is widely distributed from the Mediterranean basin, through central and eastern Europe to northern Asia. Infestations with larvae of W. magnifica (wohlfahrtiosis) have been detected in many domesticated animal species (e.g. sheep,...

“…Myiasis in pets due to C. hominivorax has been reported in dogs and cats. Nine articles reported the occurrence of myiasis in dogs in the states of Rio Grande do Sul (SPAGNOL et al, 2006;FIGHERA, 2008;SOUZA et al, 2009), Rio de Janeiro (CRAMER-RIBEIRO et al, 2003;CORREIA et al, 2010), Federal District (CANSI & DEMO, 2011;NAME et al, 2012), São Paulo (PENA, 2007) and Goiás (LUSTOSA et al, 1983). Myiasis in cats has been reported only in Rio de Janeiro (MENDES-DE-ALMEIDA et al, 2007;SOUZA CP et al, 2010a;MAROTTA et al, 2011) and the Federal District (CANSI & DEMO, 2011).…”

Cochliomyia hominivorax (Coquerel, 1858), the New World screwworm, causes primary myiasis in wild and domestic animals in tropical and subtropical regions of Brazil. Although this species is considered to occur throughout the country, organized information about its recorded distribution has not been available until now. This article aimed to provide a comprehensive review of the historical and current data published on both immature (myiasis) and adult stages of C. hominivorax in Brazil. A total of 174 articles were found; of these, 141 articles reported myiasis cases in cattle (146 records), humans (68 records), and other mammalian hosts (40 records), and captures of adult flies were reported in 33 articles. C. hominivorax is widespread in Brazil, having been recorded in 208 municipalities in all major biomes of the country.
